The timing is too improbable for plausibility.
I knew something was up when the Saudi spokesman began his press conference by saying "I just heard it on the radio; the bad guys are being pursued as we speak."
This stinks to high heaven.. They grab a guy off the street, kill him, and label him a high ranking AQ operative. "We even caught him in the act of disposing the body." Yeah right. I mean, why in the hell would the terrorists need to transport the body?!?! Logically, the assassins killed Johnson, popped the video tape out, and fled their hiding spot. You'll never convince me that they felt it necessary to take the body out in public to dispose of it. Horse crap.
